System for simultaneous transmission (1) of Morse signaling over a radio communication using digital technology, comprising: a signal generator (2) with at least one digital modulation which includes at least one amplitude modulation component; a Morse code generator (3) that generates Morse tones in analog form; a first attenuator module (4), controlled by the Morse code generator (4). In this way, a signal with digital modulation generated by the signal generator (2) is attenuated in amplitude by the first attenuator module (4), the amplitude attenuation being the function of the amplitude of the waveform generated by the Morse code generator (3). In this way the transmission of information by means of digital modulation is simultaneous with the transmission of the Morse code by means of analog amplitude modulation (AM), using one single radiofrequency (RF) carrier signal and without service interruption or information loss. |
